Fixed now.  The file comes from libtool 1.4.  Unfortunately, we have to
patch it ourselves, as the libtool 1.4 `patch release' suddenly requires
autoconf 2.50 ...

Very strange.  Configure has

  *aix4.[2-9]*)
    EXPORTFILE="\$(top_builddir)/etc/R.exp"
    cpicflags=
    cxxpicflags=
    fpicflags=
    wl="-Wl,"
    main_ldflags="${wl}-bdynamic ${wl}-bE:${EXPORTFILE} ${wl}-bM:SRE"
    shlib_ldflags="${wl}-bM:SRE ${wl}-H512 ${wl}-T512 ${wl}-bnoentry \
      ${wl}-bexpall ${wl}-bI:\$(R_HOME)/etc/R.exp"
    SHLIB_LIBADD="\$(LIBM)"
    ;;

so unless I am missing something obvious all linker flages are protected
via `-Wl,' (which should also work if the C compiler is not gcc).
